In 1840, Mr. Lafarge passed away. His young wife was accused of murdering him. After an autopsy they found traces of arsenic. A chemical that could be deadly in large doces, but is made naturally by the human body. At the same time of the "murder" Dr Orfila was giving a series of presentations on his toxicological device, dubbed the Marsh test. His test concluded that mistress Lafarge was guilty and she was sentenced to life in prison. Many people disagreed with Orfila and his colleagues test. One such person, Francois V. Raspail, strongly disagreed. He wrote many papers and published them, saying Orfila's test was a joke and the mistress should be freed. Raspail argued that the test was to far ahead of its time, and that it was not correct. Raspail put Orfila on trial, and they let the french people decide. This was the first time that the use of machines had been used to determine the cause of death.TYLER IS COOOLLLLLLLL!!!!!!!!!!!!!
